Chapter 6.5, Problem 75E

Matching Match the system of inequalities with the graph of its solution. [The graphs are labeled (i), (ii), (iii), and (iv).]

(a) $\left\{\begin{array}{c}{x}^2+y^2\le 16\\ x+y\ge 4\end{array}\right.$ (b) $\left\{\begin{array}{c}{x}^2+y^2\le 16\\ x+y\le 4\end{array}\right.$

(c) $\left\{\begin{array}{c}{x}^2+y^2\ge 16\\ x+y\ge 4\end{array}\right.$ (d) $\left\{\begin{array}{c}{x}^2+y^2\ge 16\\ x+y\le 4\end{array}\right.$
